Description
Technical field
The utility model relates to the milling friction stir welding connection area of large-scale melon lobe longitudinal joint, particularly relates to a kind of for melon lobe part longitudinal joint milling agitating friction welding frock.
Background technology
Friction stir welding is a kind of novel Material Joining Technology.Make material to be welded be in a kind of fritting state in commissure by the High Rotation Speed of mixing needle in commissure and fricative heat, by the effect of mixing needle, the material on weld seam both sides is linked together afterwards.Because material does not melt completely, doing so avoids the generation of the defect that some easily occur under melting welding state.Simultaneously can not produce the pollutants such as waste gas in the process using friction stir welding, shown in say that friction stir welding is a kind of green welding technology efficiently.Based on the many merits stirring friction weldering, increasing user selects friction stir welding to replace traditional melting welding to connect.But because friction stir welding is different with the mechanism of action of traditional melting welding, make the auxiliary mould of friction stir welding need larger rigidity, also improve the design difficulty of auxiliary mould simultaneously.
The agitating friction welding of melon lobe part longitudinal joint, because himself design feature and stirring friction-welding technique feature determine the forging force that needs to support mixing needle at the supporting die tire of melon lobe fitted underneath high rigidity.The laminating degree of mould tire and workpiece very broad aspect have impact on the quality that agitating friction welds.Simultaneously in stir friction welding process, there is very large tension force the both sides along weld seam, need to be overcome by side tension by the hold-down mechanism of frock.Due to front production process and the design feature of self, often there is position while welding camber line low precision, the problem that deflection is large, need frock to give certain rectification in melon lobe part.6 pieces of melon lobes are finally welded into as a whole, if a point block welding can cause overall precision step-down, there is the risk causing last one weld seam to weld because precision is too low.If the milling of melon lobe and welding be not in same frock, secondary assembling easily causes rigging error.
Summary of the invention
For problem existing in existing melon lobe weld parts frock, technical problem to be solved in the utility model designs a kind of multiple-pass weld that can simultaneously complete to compress with closed device to reduce installation time, and raising efficiency of assembling ensures welding quality and precision simultaneously.
The utility model for the technical scheme solving its technical problem and provide is: it is characterized in that, comprise: circular base, the some pieces of melon lobe installation mould tires arranged around described base, several install the welding supporting die tire between mould tire at adjacent two melon lobes, and be arranged on some weld seam hold-down mechanisms of described melon lobe installation mould tire outer wall and middle hold-down mechanism, described weld seam hold-down mechanism is installed mould tyre bead edge along described melon lobe and is arranged, and described middle hold-down mechanism is arranged on described melon lobe and installs in the middle part of mould tire.
In the utility model preferred embodiment, some pieces of described melon lobes are installed mould tire and are spliced to form fornix shape radome structure on described base.
In the utility model preferred embodiment, there is gap before installing mould tire in adjacent two pieces of described melon lobes, arranges a welding supporting die tire in every interspace.
In the utility model preferred embodiment, described weld seam hold-down mechanism and described middle hold-down mechanism are distributed with some compressions point, described compression point protrudes and arranges.
In the utility model preferred embodiment, when described weld seam hold-down mechanism or described middle hold-down mechanism are tightened, some described points that compresses form the normal direction that extruding force direction is described compression point place arcwall face.
In the utility model preferred embodiment, described weld seam hold-down mechanism and described middle hold-down mechanism are strip structure, and its one end is fixed, and the other end is stretched by thread forms and provides thrust.
In the utility model preferred embodiment, each described melon lobe is installed mould tire and is all arranged on the guide rail of described base.
In the utility model preferred embodiment, described guide rail end is also provided with positioner.
In the utility model preferred embodiment, each described melon lobe is installed mould tire and is all moved along guide rail by pneumatic system.
In the utility model preferred embodiment, described lead rail axis passes through described base circle centre position to extension line.
In the utility model preferred embodiment, described welding supporting die tire is fixedly installed on described base.
A kind of melon lobe part longitudinal joint milling agitating friction that is used for welds frock, and this frock forms by welding supporting die tire melon lobe installation mould tire middle hold-down mechanism weld seam hold-down mechanism base.Its several melon lobe installs mould tire and welding supporting die tire is arranged on base, and several melon lobe parts are installed to several melon lobes by middle hold-down mechanism and install on mould tire, and then weld seam hold-down mechanism mechanism is by Work-sheet pressing.Wherein melon lobe installation mould tire is connected with adopting pneumatic system between base, automation can realize opening and closing of several melon lobes installation mould tire, when being in open configuration, producing gap between melon lobe part adjacent between two, realizing the milling of workpiece position while welding.After milling completes, several installation mould tires close, and under closure state, workpiece is connected between two, and position while welding is just on the working surface of welding supporting die tire, can disposable welding 6 longitudinal joints.Melon lobe hold-down mechanism is based on melon lobe quasi spline, and each compaction direction compressing point is all the normal orientation of this place profile, and hold-down mechanism coordinates the profile can well correcting melon lobe part with mould tire, and ensures that melon lobe part and mould tire are tightly fitted.Same melon lobe part has multiple melon lobe hold-down mechanism to compress, effectively can overcome the tension force of weld seam both sides in stir friction welding process like this.The weldment that welding supporting die tire is as a whole, ensures overall precision and intensity.
Existing melon lobe weld parts frock mainly exists that clamping is loaded down with trivial details, inefficiency, needs multiple clamping repair to weld.The utility model adopts the structure of integral type, the milling of weld seam welding to be incorporated in a frock and once to complete the welding of all weld seams, ensure that welding precision, improve the welding quality of weld seam and greatly improve welding efficiency.
